7. Regularity up to the boundary for some degenerate elliptic operators.

Author

Di Fazio, G., Fanciullo, M. S., and Zamboni, P.

Subjects
*ELLIPTIC operators, *ELLIPTIC equations, *VECTOR fields, *DEGENERATE differential equations
Abstract

We consider a class of severely degenerate elliptic operators and establish a Harnack inequality up to the boundary. As a consequence, we get smoothness of the weak solutions under very sharp assumptions regarding the lower order terms of the operator. [ABSTRACT FROM AUTHOR]

12. Unique continuation of positive solutions for doubly degenerate quasilinear elliptic equations

Author

Giuseppe Di Fazio, Fanciullo, M. S., and Zamboni, P.

Subjects
Grushin operator, strong A-infinity weights, lcsh:Mathematics, Stummel-Kato classes, lcsh:QA1-939, unique continuation
Abstract

We consider quasilinear elliptic equations that are degenerate in two ways. One kind of degeneracy is due to the particular structure of the given vector fields. Another is a consequence of the weights that we impose to the quadratic form of the associated differential operator. Nonetheless we prove that positive solutions satisfy unique continuation property.

21. A Density Result on the Space VMOω.

Author

Pardalos, Panos, Giannessi, Franco, Maugeri, Antonino, Caruso, A. O., and Fanciullo, M. S.

Abstract

In Carnot-Carathéodory metric spaces related to a family of free Hörmander vector fields X1,...,Xq, we prove that the space C∞ is locally dense in VMOω with respect to BMOω norm. [ABSTRACT FROM AUTHOR]
